  • Device and method to measure bulk unconfined properties of powders
    Patent number: 9182333
    Abstract: A method testing physical properties of bulk powder materials uses acceleration forces induce a change in physical configuration of a powder sample. Various different properties may be determined by relationships between the applied acceleration and the associated detected change in configuration event. In various embodiments powder strength, friction angle, or other properties may be determined. Novel methods and devices are provided.

  • Mixture segregation testing devices and methods
    Patent number: 8467066
    Abstract: Methods and devices are provided to measure segregation in solid particulate mixtures. Light energy is projected through a transparent barrier and reflected off a surface of a mixture volume. The constituent fraction in the mixture is determined by analyzing the mixture reflected light as a combination of the constituents' known reflected light spectral contents and intensities. This is accomplished at multiple surface locations to provide constituent fraction data over the mixture volume surface.

  • Device and Method to Measure Bulk Unconfined Yield Strength of Powders Using Minimal Material
    Publication number: 20120154809
    Abstract: A method bulk strength of powders uses acceleration forces to compact the powder into a small conical test cell that is rotated at high speed. Once the material is consolidated to a prescribed condition, the rotation is stopped, the outlet of the cell is exposed, and the cell is rotated again at increasing acceleration until material freely exits the cell. The forces generated on the powder in the cell are determined and used to compute the cohesive strength of the bulk material.
